I've been trying to solve cubic equations, but I don't know if there is a general approach that always works. Is there a specific method for solving cubics that doesn't involve the cubic formula?

2You can use trigonometry instead. – markvs Sep 03 '20 at 08:34

1There is a general approach that always works - see wikipedia (General cubic formula, trigonometric and hyperbolic solutions etc.) Also, search this site for more, e.g., here with an example using trigonometry. – Dietrich Burde Sep 03 '20 at 08:42
